Mendel's Laws Video & Questions

How do scientists refer to the first generation of a genetic cross?

• P1 generation

• F1 generation

• F2 generation

• S1 starting group

How do scientists refer to the second generation of a genetic cross?

• P2 generation

• 2nd level cross

• F2 generation

• F1 generation

What was the surprising outcome of the F2 generation during Mendel's experiments?

• None of the offspring in the F2 generation survived.

• All the pea plants in the F2 generation were tall.

• The offspring in the F2 generation grew faster than any other plants.

• The hidden traits reappeared in the offspring in predictable percentages.

A pea plant is heterozygous for yellow peas (Yy). When the pea plant forms gametes, some gametes will contain the Y (yellow) allele, and some will contain the y (green) allele. Which of Mendel's Laws does this example demonstrate?

• Law of Dominance

• Law of Segregation

• Law of Alleles

• Law of Independent Assortment

In pea plants, the allele for purple flowers (P) masks the allele for white flowers (p) in heterozygous individuals (Pp). Which of Mendel's Law does this example demonstrate?

• Law of Segregation

• Law of Dominance

• Law of Independent Assortment

• Law of Flowers

In pea plants, there are plants can be tall with purple flowers, short with purple flowers, short with white flowers, or short with white flowers. This is because the allele height does not affect the allele for flower color when it comes to inheritance. They are inherited separately, and one does the impact the other. Which of Mendel's Laws does this example demonstrate?

• Law of Independent Assortment

• Law of Segregation

• Law of Dominance

• Law of Flowers
